Lapses in procedures aimed at fighting infections are common in ambulatory surgical centers, a study shows. The lapses include safe hygiene methods and improper handling of medications and equipment.
The study by the CDC is published in the June 9 issue of The Journal of the American Medical ... Read More
In the event of an infection, the immune system releases messenger substances. These molecules can either activate immune cells to defeat invading pathogens, or inhibit them to prevent an excessive immune reaction. For this, the immune system has to decide very quickly what mixture of activating... Read More
"Drug firms 'encouraged world health body to exaggerate swine flu threat'," screamed Britain's Daily Mail newspaper on June 4. "2 European reports criticize WHO's H1N1 pandemic guidelines as tainted," headlined The Washington Post the next day. To judge from media coverage last week, a major sc... Read More
How safe is the food we get from restaurants, cafeterias and other food-service providers? A new study from North Carolina State University -- the first study to place video cameras in commercial kitchens to see how precisely food handlers followed food-safety guidelines -- discovered that risky...

Purdue University scientists have improved a strain of yeast that can produce more biofuel from cellulosic plant material by fermenting all five types of the plant's sugars.
Nathan Mosier, an associate professor of agricultural and biological engineering; Miroslav Sedlak, a research assistant... Read More
Any gardener has seen it happen. One plant in the backyard thrives, while its neighbor of the same species is plagued with infection. Why?
One reason may be genetic. Researchers have discovered that more resistant mouse ear cress plants have a variant of a gene known as ACD6. Plants with thi... Read More
Tuberculosis (TB) is an enormous global public health problem. Migration and failure by governments and the public health community to adequately treat and prevent TB among migrants is an important barrier to TB control.
To reduce the incidence, spread and severity of tuberculosis, government... Read More
Traditionally, biology is about taking apart things like cells to better understand them. For the geneticist George M. Church, the main objective is to put the pieces back together.
Strolling through his laboratory, one of the larger ones at Harvard Medical School, Dr. Church, 56, points out... Read More
Science blogger Cesar Sanchez of the site Twisted Bacteria (twistedbacteria.blogspot.com) reviews the American Society for Microbiology's use of social media during their general meeting and also highlights several tweets coming from attendees:

While its widespread application in law enforcement is still years away, scientists at the University of Colorado, Boulder have developed a technique that can match the “personal” bacteria on an individual’s hands and fingers with bacteria deposited on computer keyboards and mice. Once perfecte... Read More
Researchers at McGill's department of natural resources, the National Research Council of Canada, the University of Toronto and the SETI Institute have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North. Dr. Lyle Why... Read More
Nashvillians who lived during the 1918 flu virus could save lives if the world were hit with a similar deadly pandemic.
The 1918 virus, known as the Spanish influenza, claimed at least 50 million lives worldwide and wiped out 5 percent of the U.S. population. More than 13,000 Tennesseans died... Read More
Scientists at the Genome Institute of Singapore (GIS), a biomedical research institute of the Agency for Science, Technology and Research (A*STAR), and their colleagues from the National University of Singapore, Nanyang Technological University, Duke-NUS Graduate Medical School and Princeton Uni...

Microbes are certainly being exposed to oil in the Gulf—both on the surface and at depth—and they are the first responders. Although many microbiologists naturally are interested in the identities of the oil degrading bacteria, this is of less relevance than the chemical changes the mixed microb... Read More
Three-dimensional imaging is dramatically expanding the ability of researchers to examine biological specimens, enabling a peek into their internal structures. And recent advances in X-ray diffraction methods have helped extend the limit of this approach.
While significant progress has been ... Read More
Researchers have discovered components of the bovine mastitis-causing bacterium, Streptococcus uberis that play a key role in the disease. This discovery could lead the way to finally developing a vaccine for this endemic disease, which costs UK farmers alone nearly £200M per year, requires the ... Read More
Erik Georg Granquist's thesis examines infections caused by the bacterium Anaplasma phagocytophilum in lambs. This bacterium is the cause of the disease tick-borne fever in ruminants and granulocytic anaplasmosis in humans. The bacterium is transmitted by ticks and is the indirect cause of consi... Read More
Some species of bacteria perform an amazing reproductive feat. When the single-celled organism splits in two, the daughter cell - the swarmer - inherits a propeller to swim freely. The mother cell builds a stalk to cling to surfaces.
Univ. of Washington (UW) researchers and their colleague at... Read More
It's enough to make a techie iGag.
Some of the sleek new iPads users play with at city Apple stores are laced with potentially dangerous bacteria or are just plain dirty, a Daily News investigation revealed.
Of four iPads that were swabbed in two stores last month and then tested in a lab,... Read More
An award-winning venture by a University of California - Davis student team could turn a public health pariah into a potential hero, using tobacco plants to develop vaccines in weeks instead of months.
The team, Inserogen, won the $15,000 grand prize at the Big Bang business plan competition ... Read More
